^ There's a fine balance between that, really...
Almost no game is fun when all you do is pwn noobs every damn minute you're playin'. On the contrary, depending on the game, playing against godly players constantly can get very boring over time. Or at least, that's how it goes for me.
For example, in some games, "the winning strategy" is only one typical strategy. Anything other playstyle puts you at a severe disadvantage; the kind of disadvantage that when gaming with other players at your skill level, will end with you gettin' your ass kicked.
For example, in Red Dead's Gold Rush competitive mode (essentially Capture the Flag; or in this case, bags of gold), if you actively and as quickly as possible go for the bags, you'll get shot in the back as soon as you pick it up and are unable to do any action for a good second when picking up said bag. If you do nothing but camp around the bag drop-offs waitin' to steal bags from other players, you'll be the one getting shot from behind by a camper who wants to take your place nine out of ten times.
To win, you need to do a combination of capping bags by predicting which bags people won't go for, and then camping to wait for someone with a bag to pass by after you captured your own. After about 200 matches, this rinse-repeat strategy gets... monotone.
Variety is the spice of life, and gaming as well. All those hackin' proxyton scrubs will get bored of using the same uber loadout if they use it EVERY game; especially since they didn't earn their way up and play the game with different weapons.
